About
ToolRoster
ToolRoster is a growing catalog of 168 free calculators, converters, generators, and practical work utilities.
What this site is for
ToolRoster is built for quick, repeatable tasks: calculating finance numbers, converting files, formatting developer data, drafting operational templates, and checking web or business inputs without opening a heavy app.
The tools are designed to be fast and direct. Most browser tools run from structured tool definitions, and file conversion tools return downloadable output from the server when a local browser-only conversion is not practical.
How the tools are maintained
Tool definitions are kept in a registry so the website, API examples, generated docs, and regression tests all use the same source of truth. That reduces drift between what the page says and what the tool actually does.
ToolRoster is still evolving. If a result looks wrong or a converter fails on a file that should work, send the details through the contact page so it can be fixed.
